Almighty reader fathers: Hello! My name is Zhao Xi, and I am a special agent. During a mission, in order to cover my teammates, I was bombed to Taiwan in the parallel world of 1279. At the beginning, we were attacked by pirates and natives. We finally solved it and got dozens more mouths... Taiwan in this era was really poor, tens of thousands of years behind the Stone Age...

But now, I'm running into a little trouble, My public relations department accidentally destroyed the Yuan Dynasty. What country should I name? Waiting online! Quite urgent!
